STERILIZER ATTACHMENT FOR HYPOIDERMIC SYRINGES.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed April 21, 1916, Serial No. 92,669. Renewed March 8,1919. Serial No. 281,555.

To all whom it may concern:

Be it known that I, Gus B. YOUNG, a citizen of the United States, andresident of Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful Sterilizer Attachment for HypodermicSyringes, of which the following is a specification.

The object of my invention is to provide an attachment for hypodermicsyringes of simple, durable and inexpensive construction.

A further object is to provide such an attachment comprising areceptacle, and means for adjnstably mounting the receptacle on thesyringe barrel in line therewith, so that the needle will be receivedwithin the receptacle.

A further object is to provide means for locking said receptacle on thesyringe barrel if desired.

A further object is to provide such a device which can be quickly andeasily removed from the syringe to permit the ordinary use of saidsyringe.

My invention consists in the construction, arrangement and combinationof: the various parts of the device whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawinns, in which:

*igure 1 shows a side elevation of a hypo dermic syringe with my deviceattached thereto, the receptacle being shown in section.

Fig. 2 shows a side elevation of a syringe with a modified form of mydevice partly in section installed thereon.

In the accompanying drawings, I have used the reference numeral 10 toindicate generally the barrel of an ordinary hypodermic syringe, havingat one end the removable cover 11. Screwed into the cover 11 is a shankof a needle 12.

My improved attachment comprises a comparatively deep receptacle 13having one open end. Secured to the receptacle on opposite sides of theopen end thereof, are parallel spring metal arms 1 1, extending alongopposite sides of the barrel 10 and having at their free ends curvedgripping members 15. The receptacle is of suiiicient diameter to receivethe lower end of the syringe.

in the practical use of the device just described, when is desired toprepare a solution for use with the syringe, the members 15 are slippedon to the barrel of the syringe. ater is poured into the receptacle 13and is heated. The receptacle is quite small, so that an ordinary matchmay be used for heating the water in said receptacle. A tablet may bedropped into the receptacle and dissolved after the water has beenboiled and a medicinal solution may thus be formed.

The plunger stem 16 is drawn outwardly, thereby drawing the solution 17into the syringe. The attachment is then slipped ofi. It will beunderstood that the arms 14 are of resilient metal, so that theattachment may be readily removed from the syringe and so-that they maybe used on syringes of difi'erent diameters. The syringe is then readyfor use, the needle has been thoroughly sterilized, and the water usedin the solution has been boiled. The attachment is longitudinallyadjustable with relation to the barrel of the syringe, so that thereceptacle 13 may be readily and easily usedwith needles of differentlengths.

In Fig. 2, I have shown a slightly modified form of my device in whichthe removable cover 11 is removed and an externally screw-threaded cover18 of greater diameter than the member 11 is substituted for it. In themodified form the upper portion of the receptacle 13 is internallyscrew-threaded to coact with said cover member 18.

The receptacle, which is indicated by the numeral 13, may be screwed todifferent positions on the barrel of the syringe for securing thereceptacle in diiierent positions.

The form shown in Fig. 2 is especially desirable "for use underconditions where it is desirable to lock the receptacle in position forprotecting the needle. All of the forms are adjustable. as shown, foruse with different needles.

The advantages of an attachment such as that herein shown are largelyobvious'from the foregoing description.

It is very easy to boil 2. very small amount of water for making asterilized solution and for sterlizing the needle.

The solution is prepared in the receptacle and is drawn into thesyringe. It is easy to keep the needle from any contaminating contactuntil after it has been used.

The attachment is comparatively simple and inexpensive, and as shown,easy of operation, so that any one can use it.

It will readily be seen that changes may be made in the construction andarrangement of the parts of my improved device without departing fromits essential features and purposes, and it is my intention to cover bythis application any such modifications of structure which may bereasonably included within the scope of my claims.

I claim as my invention:

1. In a hypodermic syringe, a syringe barrel having a screw-threadedmember, a receptacle open at one end having a screwthreaded portion atits open end adapted to coact with the screw-threaded portion of thebarrel, arms projecting from the free end of said receptacle anddesigned to stand alongside the barrehmade of resilient material, eachof said arms having at its free end a gripping member, adapted toyieldingly engage said barrel, whereby the receptacle may be secured onto the barrel and when relieved from its screw-threaded engagement, mayhe slid longitudinally with relation thereto, so that said arms willhold said receptacle in different positions with relation to the barrel.

2. In a device of the class described, the combination of a barrel withan attachment comprising a receptacle open at one end adjacent to saidbarrel, arms on said receptacle adapted to extend alongside said barrel,and to be slidably extended thereon, and means for detachably securingsaid attachment to said barrel.

3. In a device of the class described, the combination of a barrel withan attachment comprising a receptacle open at one end adjacent to saidbarrel, arms on said receptacle adapted to extend alongside said barreland to be slidably extended thereon, and means for detachably securingsaid attachment to said barrel for limiting such sliding movement.
